Quite happy with how the chain has performed, though I am certainly no sort of bike guru--I just ride a lot. I don't race, I do put up quite a few miles (7200ish for 2019). Shimano is of course out now with their 105 R7000 stuff. Wondering if I should go with that, or look at Ultegra or the Dura Ace option. I do quite a bit of climbing--it is quite hilly/mountainous here in Western Oregon. Conditions here usually later October through and into May are extremely wet and grimy. It can literally destroy a bike, if you don't take care. I clean the drivetrain farily well after every ride and very thoroughly once a week without fail and keep it generously lubed, so I do think I am basically doing my part. It is not making any noise--it is utterly silent, but it is time, based on miles.

Anyhow, would appreciate recommendations on what my next chain should be. Many thanks for taking a minute to help me out.
